To czZZ 'whom it may concern.'

Be it known that I, HARM FRANZEN, a citizen of the United States, residing at Mabton, in the county of Yakima and btate oll Washington, have invented certain new and useful Improvements inl Runners. for Sickle-liars, of which the following 1s a specification.

This invention relates to attachments for mowing machines, and the primary object of the invention is to providean improved support for the cutter bari" of a mowing ina chine, so as to prevent the guard teeth of the bar from biting into the ground and becom ing brolren when the ordinary supporting shoe of the bar rides into a ditch or other irregularity in the lield.

Another object of the inventionis the pron vision of an improved runner for thecutter bar of a mowing machine which is adapted to be positioned intermediate the usual. supporting shoes and is so arranged on the 'bar 'for holding the saine in an elevated position, when the supporting shoe Jfalls into a ditch or the like, thereby providing an attachM ment which is especially adapted for ma# chines, used on fields having small irrigating ditches therein.

A further ob ect of the invention is the provision of an improved runner for the cutter bar of a mowing machine embodyn ing an arcuately curved plate adapted to be securedto the cutter bar intermediate the 'usual supporting shoes and arranged to engage 'the ground in the rear o'l the cutter bar and the supporting shoes. t

A still further obje/tt oit the invention is the provision of an improved attachment lier cutter bars of mowing machines otthe above character which is durable and eiticient in use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

Uther objects oE the invention will appear in the following detailed description, talren in connection with the drawings, forini ng a part ci this speciication, and in which drawings Figure 1 is a perspective view o ii a mowing machine provided with the improved ruimer.

Fig. Q is an enlarged detail transverse section through the cutter bar and iin proved runner taken on the line 2-2 of Fig. 3. I

Fig. 3 is a tragmentary plan view of a cutter `bar showing the improved `runner applied thereto, and

Fig. fl is an enlarged fragmentary detail section through a cutter bar, showing a slightly modiiied type of runner applied thereto.

Referring to the drawings, in detail,

`wherein similar reference characters desigwhich are secured to the cutter bar in the ordinary manner, and the cutter bar is pro- `vided at its terminal with the usual supporting shoes or runners G.

The improved runners C arebolted or otherwise secured to the cutter bar`B intermediate its ends, and adjacent to and in spaced relation to the supporting shoes 6 and each includes a relatively narrow elongated body 7 formed of any material, but

preferably of resilient steel. The elongated body 7 includes the downwardly and rearwardly extending portion 8, which has its inner end bent upwardly, substantially at right angles as at 9 into engagement with the rear face ot the cutter bar and then forwardly at right angles to provide the attaching 'loot or portion 10. The attaching i'oot 10 is provided with a bolt hole 11, by means or which the runner is adapted to be secured to the cutter bar. It so desired, the bolts for holding the guard fingers 5 may be utilized 'for holding the runners C in posi tion and in this instance the bolts are e2ttended through the opening 11, or if so desired a separate bolt l2 may be provided and extended through an aperture 1?, formed in the cutter bar intermediate the guard ngers 5. The right angular portion 9 oli the runner C is provided with an inwardly struclr out tongue 14, which is adapted to engage the face of the cutter bar` opposite to the 'face engaged by the attaching portion 10, and forms an additional support J.tor the cutter bar so as to prevent an undue strain on the bolt 12. It so desired, the attaching foot l0 may be secured to the lower surface o'f the cutter bar, and in this instance the tongue 14 is struck out and bent upwardly and forwardly into engagement with lthe upper surface of the cutter bar.

rl`he lower rear end yont the runner C engages the ground a suitable distance in the ear of and below the cutter bar Aand has Vits rear end bent slightly upwardly as at l5.

ln F t is illustrated a slightly modified form of the inventionin which form the runner C is attached to the lower surface of `the' cutter bar intermediate the linger .guards 5, andthe same is held in place by a -.vented, owing to the position of the inner Y end of the runner between the shanks oi the guards 5, which prevents any lateral movement thereof. In this instance, the runner may alsoloe bolted to the upper surface of the cutter bar if so desired;

The improved runners C are particularly7 adapted for mowing machines, which are used on fields which are irrigated byv small ditches, where the teeth'or guard tingers are Vv-very apt'to be broken when the supporting shoes or runners 6 ride into the ditches.

,in vuse of the improved runner, the same being positioned intermediate the shoes and in the rear thereof, effectively supports the cutter bar when the ordinary shoe rides into a ditch, thereby preventing the guard fingers from digging into the ground and becoming brokenc The runnei's'areralso particularly adapted for Vuse on fields, in which the ground is broken or irregular, and as clearly shown in F ig. 2 when the ordinary shoe or cutter bar rides into a depressed portion of the ground, the improved runner C will support the cutter baruntil the shoe rides out 1 of the same.

jFrom ther-foregoing description it can be seen that an improved attachment is provided for Vcutter-bars of mowing machines .which is .exceptionally durable and efficient in'use, which will support the cutter bars and prevent the guard lingers from digging into the ground and becoming broken.

lChanges in detailsmay be made without departing from the spirit or scope of my invention 5 but,

I claim:

l. ln a mowing machine, the combination with a cutter bar including the usual supporting shoes, ot an attachment therefor secured to the cutter bar intermediate its ends and adapted to engage the ground in rear of and below the cutter bar.

2. In a mowing machine, the combination with a cutter bar havine its terminals provided with supporting` shoes, oi a runner attachment therefor including a pair ot spaced plates curved transversely and secured to the cutter bar intermediate the supporting shoes. and arranged to engage the ground in the rear of the cutter bi and supporting Shoes.

3. ln a mowing machine, the (':oinbination with a cutter bar inclu-ding a pair oi" supporting shoes. ot a ruimer attachment therefor secure-d to the cutter bar intermediate its ends and extending downwardly and rearwardly therefrom.

l. in a mowing` machine, the combination with a cutter bar haring a p 'r ot supporting shoes, oit a ruimer therei'or including an elongated body having a forwardly extending attaching portion arranged to be securel to the cutter bar, the body being curve-,l downwardly and rearwardly and arranged to engage the ground in rear of the supporting slices.

5. ln a mowing machine, the combination with a cutter bar having a pair ot supporting shoes, of a runner thereior including an elongated body l vineI a forwardly extending` attaching foot adapted to be secured to the cutter bar, a struclr up tongue cairiezl by the bony and arran ed to ein re the opposite tace ot the cutter i ar opp ite to the attaching portion, the body o'f the runner extending downwardly and in the rear ot the cutter bar.

6. A.. ruimer for the cutter bar ot mowingl machines including an elongated cnri'ecl body having aV forwardlyextending attaching toot.

l. runner including a iliit elongated narrow body incliuling` a downwardly and rearwardly curved portion and a i"e.r\\`ardliextending attachingV toot, and a .struck un tongue'carried by tl e. ltody and arraingjed below the attaching foot.
